@ASTER-BRACKET SOCKET FOR" CHANNELED IIEGS.

Applicattonxled .'funeffl, 1925. Serial No'. 365871".

This inventionl relates to an .inside bracket consti-notionA lor4 legs .suoli as angle iron legs having a. channel or groove, therein. receiving' said hraohet construction i in turn receiving a. caster.;

The chief: object ofl the invention is to provide a bracket construction. which. may bel readily. attaohed toiand.v when attached, rigidly seoni'edi to the inside` of a. channeled le@snohaasfachannelior angle. iron or` similari` leggi constrnetions, Which1 bracket construction: is adaptedto support a cast-er stein ori pedal.

The" chiel` feature. of.` the invention consists in associating a tubular socket with a clami'iinginemben engaging oneside of the soelret: for olamping theisocket tothe leg at* theinside. ofthe. channel thereof, which clainpingf construction may. be and` preferably` is readily.v insortible or' positionable apen the channeled leg and'ismovedinto olainpingj engagement.. withY the socket by the insertion` of the socket. in` the poclret termed. betiveenthe clamping. member and the-leg.

Another 'feature ofthe invention consists inthe arrangement. oftthe `parts. whereby the channeledllegf;includes. but apair ollongitiidinally extending4 slotsnear. the bottom end thereoivyhi'ch slots aretpreiterably substantialli7 paralleland lie/in opposite faces oi the 4channeled'.leg orin the opposite faces oi the angle` leg., p

Another. feature oifthe invention is that the soelret clampinggly supported liv the clamping member' iipon the leg, is limited in.longitudinalmovement along the leg by engagement. of "the base ot said socket `with the:bottomofthe leg. or engagement of the base. otsaid socletfivith the bottom of the Clamping-.member or b v the engagement oi tlieibase of the said'socketA Withthe blot-tom ot' the .leg4 and.'` the clamping. member as desired.

Still a further. feature of." thev invention consists in' the. ntiliation of a tubular sock-et formed from a single piece of? metal and having atleast one. and preferably not more than tvv-o longitudinal lines ot separation and the associating a socket. of. the character describedi with a clampingr construction Which extendsl substantially the fell length. otthe` socket for forming a pocket extendingVV substantially' the full length of the socket'ifor receiving the same and preventing' opening"inovenientf of said tubular Socket having the longitudinal edges specified;

Ainothenfeature off the invention consists inthe addition oi? an1 overlianginghood, if desirerh. which isf noty only ornamental but also'may. serve when necessary o1" desired; to limiti longitudinal linoven ient of the socket along the leg in theevent that socket en; gagementl with the bottom off the leg or bottoni of? theelamping i'i'iember` is not? desired.' Snell a construction, therefore, per'- inits the soelretto be*n inonntedi above the bottoni of the legnvherefven suoli mountings are-neeessary` or desirable.

In the drawings 10 indicates an angle iron leg having a channel 11 formed by the sides thereof, and said angle iron leg includes edges 12, an exposed face 13 and an inner face 14. Herein extending through each side of the angle iron leg and adjacent the bottom thereof is an elongated slot 15. This slot 15 is of considerable width as shown. Herein a pair of slots 15 are illustrated,one in each side of the angle iron and in substantially parallel relation. These slots may be formed by milling or punehing or in any other suitable way, and herein they are shown extending longitudinally of the leg and lie substantially in common planes and parallel to the bottom of the leg.

There 'is herein illustrated a socket which may be of any conventional type7 of which there are several7 but herein the same is illustrated as formed from a single piece of sheet metal which is bent back upon itself providing a plurality of pairs of abutting edges 16 to form a tubular socket 17, having the head portion 19 which is the connection between the sides of the socket. The ends of these sides forming the tubular socket are turned angularly as at 18 and form a base portion. rl`he connection between the base and thesocket portion is preferably curved so that the mouth of the socket is bell shaped.

The bracket or clamping member is as- Socia-ted with a leg of the character described and a socket of the character described and these legs and sockets in the several views are shown substantially iden tical. The several figures illustrate diii'erent forms of clamping members.

ln Fig. 3 there is illustrated in plan the development of one forni of clamping mene ber shown in operative relation in Figs. 1 and 2. Herein the body portion 2O includes a pair of opposite extensions and 22. rlhe extensions 21 and 22 are not oit the saine length. Each of the extensions. however. is provided with an angularlyv turned portion 23 at its outer edge. s shown clearl)v 1n Fig. 2 the width of the slot l5 in the legl is sutiicient to permit the passage of the angular portion 28 of the extension 21 or 22.

In Figs. 1 and 2 it will be observed that the bodv portion 2O of the clamping inentber is showh curved. rlhe curvature is preterably greater than degrees and less than 180l degrees although a lesser angle or a greateriiangle may be employed witlliout departing` from the broader 'teatures of the invcntion.

The method of mounting the bracket construction is as follows: The elongated extension 22 with its angularly turned end 2-l is passed through one of the openings t5 until the side edg s of the body portion 2l eugagc the innen wall 14 of the leg. liheu 1n this position the extension 21. with its angular end 223 is in registration with the other slot 15 in the other side of the leg. The extension is then passed through the slot and the bracket is retracted from the [iin-5, slot. that the extension 22 is returned un til the angularly turned end 29 thereof engages the outer side 13 of the legl at the same time the other a7 idarly turned end L eugages the outer .e 13 of the other side of the leg. Therea'iter the tubular socket inserteduin the pocket formed b v the aujle et the angle iron leg. The clamping nieulier and it Vis driven into the, sante and the di me ons of the, three pa tjowit. the leff. cianiping member and socket, are .such that frictional engagement is s l which is ecureu suiiicient to maintain the clamping' nieiuber in clamping position and clanuiing rehtion. nounted upon the angle iron leg. and tu vieldingly retain the socket upon the leeg. Longitudinal movement of ther socket `within the pocket thus formed is liiuite'l b v the engagement of the base 18 of said toeliet with the bottom edge of. the leg` or with the bottom edge of the body portion 29. or both, as shown in Figs. 1 and ln Fig. 6 there illustrated another forni of the invention which includes a bodxv portion having a pair of extensions 121 and 122. each of which is provided with an angular end 123. This forni ol' the inven- Cit b' il lut) T13016 inclusive. Inthisform of the inventionlthebody portion 120 is curved and the curvature. is slightly greater than that shown-z.inyFig.` 2 althoughit may be less thaniorfgreaterz'thanthe same.V The dimensions andi` relationship are such that the clamping; memberA a' when l; positioned within the 'angleisi constructed sucht` that the et tensions 121 andv 122ravl1en their angular ends 1123 will just pass through the slots.

In Fig; 13 anglefiron 110 is'showni proL videdawith ab single slot115 which isat fthe. corner oit thelegalthough it is notfnecessan" ilyfpositioned at this point. This positionp-- i. permits the singletransverse opening to be iorined by punching or by milling; as. desired. Associated with. this formsof' the invention is a socket 17 "havinpgsltthe capi` 19 and base 1S all as'heretoforedescribed.4 The `bony portion I ofthe clamping. or braellfct members-includes the extensions @4122i and 121 which are provided with angularly turned ends 1423. i In this orrnlof itheiin- Vention the bracket is U-shaped withl its two sides `positioned in closer"relationship' than the width* oil'the socket so thatl the ends 422 are passed through the slot "115 oi'1 the" leg* 110.

lu Figs. 15 and 16a tui-therniodi'ed form is illustrated and herein. tho leiylitl" includes the single transverse slotllhatfits corner. The socket member isf the usual socket having `the base 18) tubular portiera 17 and cap portion19.` The lnclcketfmeni ber, see- Figal comprises a'lbody portion"` 520, a cap portion which is `extended las at 521 and is provided with an angularend 523i` This angularlylturned end isanfg'w larly outlined so asl totornr a pocket to engage the angularly positioned iaoesofthe angle iron; Theflower portion ofthe bodyf portion 520includes the lateral portion"522 ".ifith aneularly turned end portions 523! Herein the-angular ends522 and 523 extend inthe saine direction and likewise are`=simi` lar,` thatis, they lie inthe saine planer and'y arefsubstantially rectangular in outline. InV this iorin o'l.l the invention" the extension 521i is positioned in theslot'115 and lwhen thus= positioned the extcnsio1r522 with itsangu lar end just clears the end lof the angle iron' len' 110. Lateral movement 1oi' the `bracket,A tl'ierciore i'orces `the extension 521 througrh the opening;- or slot 115 and passes the eXtension 522 laterally ot the end of the leg untill the transvei porti`o1r523`of the extensions 521 and 522 lie in pane parallel tothe an-` Aple iorn. 1When thuspositioned thebraclut1 may be driven upwardly along the leg; and thiis the bracket is anchored to the leg. lhereaiiter in the pocketformedbetween` thc les; 'and the bracket the socket may loe` inserted and the socket will maintain the bracket in position and be maintained in po-` ,ion on the les: by the brani-:eh

r 'ffiriu oi the invention disclosed inf Figs. 15 and `1G may be further modified as lll) follows: 1t is not necessaryV that a single transverse slot be utilized, but a pair of transverse slot-s oppositely positioned may be utilized, and in this event the pair of angular extensions 521, including angular ends 523, each pass through one of the` slots thus formed. The lower extension 522 may be cup formed as shown in Figs. 15 and 16, or may constitute a pair of extensions as angularly turned ends 523 that may or may not lie in longitudinal alignment with the angular extensions 521. These various modifications ot this form of the invention will be readily apparent trom the foregoing.

In the form ot' the invention shown in Figs. 17 and 18 the angle iron 10 is shown provided with a pair of longitudinal slots 15 oppositely positioned. Herein, see Fig. 26 also the clamping bracket and the socket are integral but portions ot the same are so arranged that a clamping engagement is secured. 1n this form of the invention the socket has a. tubular body portion 117 formed by a pair of curved portions 117 a and 117, that have abutting edges 1161. he curved body portion 117a is connected to the curved body portion 117b by the top portion 119. Each of the body portions 117 a and 117b terminate in a flange or base portion 118. The body portion 117b is notched intermediate its ends as at 1161). The body portion 117a upon opposite sides is provided with the extensions 622 and 621 which termiate in angular ends 623. The notched portions 116b are adapted to seat the laterally and outwardly extending projections 621 and 622.

In Figs. 19 to 21, inclusive, a variation ot the form shown in Figs. 17 and 18 is illustrated, to-wit, a combination unitary and integral socket and clamping anchorage. In said first-mentioned figures the leg 10 includes the pair of parallel slots 15 in opposite faces. The clamping portions 720 are extended at 721 through slots 15 and the ends are angularly positioned as at 723. The wings include lateral extensions 722 underlying the end of the leg and support the same. They also limit upward longitudinal movement of theJ socket on the leg. The socket includes a body 717 having a single longitudinal slit 716 medially positioned, and integral therewith is the head 719 including reinforcing caps 718.

1n Figs. 22 to 24, inclusive, a modiiication of the 'foregoing is illustrated. ln this form the clamping members are separable trom the socket member. rlhe angle iron leg 10 has the usual notches 15 and herein the socket see Fig. 26 includes the body 817 with a head 819 and {iaps 818. The socket also has a single longitudinal opening slit or opening 816 and the walls are extended to form wings 820 which are apertured at 820a to receive the ends of clamping mem'- ber 8211 which extends therethrough and beyond the openings 15. Said member 821 has angular ends 823. rFhe body 820 incluses similar lateral wing extensions 822.

In the claims the terms channeled leg is not intended to be specific to a channel leg, but intended to include angle irons, `irons and channel irons. Likewise, the term curved referred in part to the out.- line ot the clamping portion, is intended to include not only a regular outline such as an angular arrangement, for it is peri'ectly possible to utilize a V -shaped clamping member and thus form with an angle iron a square pocket that will readily receive a tubular socket. Likewise` the term channeled7 referring to the leg is intended to include legs wherein the sides meet not only with an angle but also those with a. curvature as well. Unless specilically set forth in the claims the term tubular socket does not necessarily refer to a headed socket and unless specilically set Vforth, the term tubular socket is not intended to include a socket having an outwai-diy flanged base.

lllhile the invention has been described in great detail in the foregoing specilication and various modifications have not only been illustrated and described, but have been suggested as well, it is to be understood that these modiiications together with those which will readily suggest themselves with persons skilled in the art, are all to be considered within the broad purview ot this invention, reference being had to the appended claims.
